用matlab实现图像彩色空间RGB,LUV,XYZ,LAB之间的转换-Image RGB color space, LUV, XYZ, the conversion between the LAB

Transfer RGB image to all the other color space in the Matlab, like HSV, Lab and so on

Lab2RGB takes L, a, and b double matrices, or an M x N x 3 double image, and returns an image in the RGB color space. Values for L are in the range [0,100] while a* and b* are roughly in the range [-110,110]. If 3 outputs are specified, the
